“Fall detection left the pendant and entered the default wearable.”
Series 4 added hard-fall detection, emergency SOS, and ECG on a device tens of millions of people were already buying. It moved PERS from a stigmatized necklace to a watch.
Mass-marketized aging-in-place sensing without calling it AgeTech.
